Asynchronous read\write via serial port (App designer)

I used serial.

and used func for serial fwrite(app.s, values, 'uint8', 'async'). I could select property 'async' to write to serial port.

Matlab tells me: serial will be removed in a future release. Use serialport instead.

How can I use property 'async' for serialport? I need to write/read asynchronous via serialport.

Hi Andrei,

There is no 'async' property for serialport. In order to read data asynchronously using serialport, you can use the configureCallback function to set a callback function that will be triggered everytime a given bytes of data is available to read.

As for writing data asynchronously, the write and writeline are blocking functions and as per the changes mentioned here about changes from serial to serialport, https://www.mathworks.com/help/matlab/import_export/transition-your-code-to-serialport-interface.html it seems that there is no direct way to write data asynchronously.
